Hi There, HeyThere!
Welcome to JWN. I you have not looked around much yet, you should soon see that this is a good resource and support place for you. Most of us 'get' what you are going through.
Sorry to hear not just about your pending surgery, but the pressure to quickly get in step and follow the deadly JW blood policies.
Sounds like you have good repoire with your doc(s) and have thoughtfully thought thru the faulty blood doctrines and made your own decision about about your treatment.
Since you already know there may be an 'issue' regarding consent for blood, please do a big favor for your primary care physician, surgeon, and anesthesiologist (if possible), and let them know there may dissent from your husband and his 'clergy'. Give them the opportunity to hear from your own mouth what you will (and/or will not) accept. Letting them know of the conflict ahead of time is the kind thing to do. Trust me. And if you wait until they are prepping you for surgery, it is possible that they will already have administered narcotics or other meds. Also being minutes away from surgery, they all have other things they are preparring for.
Tell them *now* what your wishes are.
All the best for a fully and swift recovery.
